Variator sliders vs rollers

I like the idea of a slider a lot, but they don't come cheap, or in big tuning sets like the rollers do, so I've never been confident enough to order them. I'm sure your ramp plate has a lot to do with it, but beyond that I'm clueless.

YEAH DILLON, didn't you know that the stock O-ring/grease retainer you find on every derbi variator is just for show? They spent a ton of money on R&D for it just so you could make yourself look a fool on the internet some 40 years later.

Do you have any idea how much it costs to develop tooling? For example, to stamp sheet metal in multiple stages and make/alter molds to cast appropriate features in the variator to accept the part? ESPECIALLY back in the early 70's when computer aided design (CAD) was still very new and only just starting to be used for making cars, let alone mopeds? I'd wager at least tens of thousands of dollars went just into that silly grease cover...but a dollar's a penny to you apparently!

Re: Variator sliders vs rollers

I use that MRG grease still. A nice light coat. It dries and turns into a graphite powder. I think my derbi is dry. Idk, i like to lube cause i tend to find a lot of flat spots on the rollers if i don't.

I've also used like teflon spray. I think it's just nice to have it all slippy up in that bitch. Does it make a difference? i dunno. I have a really hard time just making one change at a time so it's difficult to trace.

I have sliders in my vespa. I only ever bought one set and kinda guessed what the proper weight would be based on what rollers i was running at the time. Idk, i like them but that's probably because i paid for them. The price tag doesn't really seem worth it in hindsight.

Every part? For the first derbi variant which is the example I used, I bet they did! There was nothing like it before it, you can't just pull parts from thin air. The variator grease gaurd happens to be a unique part, so it WAS indeed developed for that moped, along with probably 99% of the rest of it. They even did it MULTIPLE times for different models. For example, the clutch bells from flatreed and pp/pr are unique and non interchangeable, as is 99% of the rest of the engine.

The fact that this concept is so foreign to you is really mindblowing.
